Answer:
The scale factor is 1.5! I hope this helps!
Answer:
$138
Step-by-step explanation:
We can first turn the words into a mathematical equation by substituting words with the information we have:
Total earning - ( Price of three books)
$180 - (Price of one book x 3)
$180 - ($14 x 3)
Finally, after we have created the mathematical equation, we solve it!
$180 - ($14 x 3)
$180 - $42
$138
The probability that the sample mean is less than 30 school days will be given as follows:
the z-score is given by:
z=(x-μ)/σ
where
μ- stand deviation
σ-mean
thus the z-score of our information is:
z=(30-28)/9
z=0.222222
hence the probability that the sample mean is less than 30 will be:
P(x<30)=0.5871~58.71%
Answer:
c. y + 9 = -4(x - 4)
Step-by-step explanation:
According to the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em><em>,</em><em> </em>all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful.

Answer:
x = -8 please mark brainliest
Step-by-step explanation:
Pull out like factors :
-x - 8 = -1 • (x + 8)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-8 = 0
Add 8 to both sides of the equation :
-x = 8
Multiply both sides of the equation by (-1) : x = -8
